    Abstract: A washing machine having a broadcasting receiver for providing various multimedia contents on the washing machine is disclosed. A broadcast signal reception module is provided in the washing machine, such as a washer or dryer, which is frequently used in the user's living space. Therefore, the washing machine can not only perform a washing operation, but also output a broadcast signal. In particular, the provision of the broadcast signal reception module in the washing machine enables reception of a mobile broadcast signal, as well as a fixed broadcast signal, thereby making it possible to provide more various multimedia contents through the washing machine. Therefore, it is possible to increase customer satisfaction with a multifunction-alization of the washing machine and thus use the washing machine more universally, resulting in an increase in the competitiveness of a product.

The system includes an accelerometer used in connection with an electronic controller to sense the degree to which the appliance is not level. Signals from the accelerometer are sent to a CPU which regulates a visual depiction on a display provided on the appliance. Adjustments made to alter the leveling condition of the appliance are also relayed to CPU, thereby updating the display and conveying when the appliance is suitably level. The system components can also be used to regulate other appliance operations.

  • Patent number: 6523205
    Abstract: A clothes washing machine is automatically responsive to indications of high suds level conditions during washing operations to, not only counteract the high level of suds, but effectively educate the user on avoiding the reoccurrence of the conditions. A display, such as an LCD touch screen which is also preferably used to input desired cycle parameters, is integrated into the washing machine for both alerting the user to the occurrence of a high suds level condition and conveying information on how to avoid the development of the situation in the future. In order to avoid prematurely alarming the user, it is preferable to instruct the user only after a predetermined number of high level suds cycles are detected.

  • Publication number: 20030024057
    Abstract: A laundry appliance can be selectively operated in either manual or automatic modes of operation. In the automatic mode, a laundering operation is initiated upon receiving a single cycle input parameter from the user, preferably through a LCD touch screen display, while relying on additional operating cycle parameters established by factory preset settings or prior consumer established preferences. In accordance with a preferred embodiment of the invention, a consumer need merely select a single cycle parameter and the appliance will start based on temperature and other setting parameters taken from memory. However, even with the automatic start feature activated, the user will still be able to adjust pre-established cycle parameters by changing default values after the cycle has started.

  • Publication number: 20030024281
    Abstract: An appliance controller includes a control knob assembly and detection mechanism having various mechanical and electrical components that are configured to detect the position of the knob assembly and produce a position signal indicative of the knob assembly position. The position signal is provided to the appliance controller that produces a control signal in response thereto. The control signal is used to initiate various appliance functions based on the specific position of the knob assembly. In one form, the detection mechanism includes a variable resistor assembly that is comprised of a wiper and resistor pad arrangement. In another form, the detection mechanism includes a shaft encoder mechanism that is comprised of a light transmitter and receiver, and an associated apertured disc secured to the knob assembly.

  • Patent number: 6507967
    Abstract: A control device for a laundry appliance includes a member which need only be manually shifted through a limited range of travel, from a neutral position to which the control member is biased, in either of first and second opposing directions, to establish a desired cycle and to adjust an operational time for the cycle. The control member is provided with numerous movable contacts which are interposed between fixed contacts. Shifting of the control member a limited amount in either direction will function to engage a single pair of the contacts, while shifting the control member a further amount in the same direction causes another pair of the contacts to become engaged. In this manner, the contacts are paired to slowly increase or decrease the operational time and to also select either the next or previous operational cycle. User feedback of the selected setting is preferably provided through the use of a illuminated indicator that shifts around a track adjacent operational indicia.

  • Patent number: 6502265
    Abstract: A system for operating and programming a laundry appliance includes a menu system giving a user extreme flexibility in operating the appliance. Through a series of menu screens, the user is presented with a variety of available options. Additionally, the laundry appliance of the invention gives the user access to databases, preferably already programmed into memory of the appliance, such as general tips for laundering and simple troubleshooting. Finally, the user has the ability to program the menu system.

  • Patent number: 6460381
    Abstract: A washing machine according to the present invention includes a pressure sensor provided at a rod holding plate holding a suspension rod with which an outer tub is suspended. The pressure sensor is constructed so that a coil is wound around a magnetostrictive element whose magnetic characteristic changes when it is expanded, compressed or twisted by an external force. The change in the magnetic characteristic is converted to the change in the inductance of the coil, and an oscillating signal of a frequency corresponding to the inductance generated. Based on the frequency of the signal, the load on the pressure sensor is detected. Before supplying water, the amount of the laundry contained in a wash-and-extraction tub is detected based on the output of the pressure sensor, and an object water level corresponding to the amount is determined. After that, a water supply valve is opened to start supplying water into the wash-and-extraction tub.
